Residents in Ciudad Juarez, the epicentre of Mexico's bloody drug prohibition war, say authorities are going after small offenders and innocent people such as poor workers even as they allow powerful drug lords to operate with impunity. President Felipe Calderon is under pressure to show results in his offensive against traffickers in Ciudad Juarez where he has deployed more than 7,500 soldiers and police, making the crackdown a central part of his war on drug trafficking organizations. But rights groups say corrupt or ineffective police and soldiers have rounded up hundreds of drug addicts and ordinary people in the manufacturing city across from El Paso, Texas without making major drug busts or arresting top capos.
